There’s more spatial data, geo-processing tools, geo enabled storage and mapping tools than ever. Let’s start with storage – not too long ago geo developers had two choices, file formats or proprietary object-relational databases. Today there are production ready open source object-relational databases such as PostgreSQL/PostGIS and MySQL; even mobile devices have lightweight databases with spatial capabilities such as SQLite.
In addition to traditional object-relational databases, NoSQL databases such as Cassandra, CouchDB, and MongoDB have a spatial capabilities. Big Table clones such as Hbase can also store spatial data and there is ongoing work for developing a spatial index which facilitates spatial queries and operations. Neo4J is a graph database that also handles spatial data. Finally, even full text search engines such as ElasticSearch provide geospatial search capabilities. Mapping Ecosystem. BOOK | Web Mapping Illustrated. I will have to say I was taken aback, flummoxed, and every other descriptor when I got to Chapter 8 - 'Visualizing Mapping Data in a Desktop Program'.
I looked back at the cover of the book to make sure I had picked up the right book to read while eating. Sure enough, 'Web Mapping Illustrated'. After setting up Mapserver on my remote Fedora dist Linux server and other associated tools, Postgre SQL, etc, (seriously, thanks for the growth, I would not have learned so much about administering my server), and being satisfied working in the Linux environment, to have been thrown back to previous chapters to set the tools up on a Windows box so I could run aps on the local desktop was disconcerting.
Love learning about mapping, and using desktop tools is what peaked my curiosity about WEB MAPPING and serving up dynamic maps. Great book, and using the desktop may be the only way to teach the techniques illustrated in Chapters 8 and 9. MapWith.Us. TileMill Revisited. As a diehard lover of old maps, I have been especially excited by Map Dorkia’s recent rediscovery of the charm of bygone cartography. I came to GIS via history and archaeology, so my generalized love of maps stems from an earlier, more specific love of old maps. I think this also accounts for the fact that while maps come in many shapes, I am most fond of the ones that depict an actual physical landscape. So I was thrilled a short while ago when Kartograph arrived on the scene (skillfully showcasing a stunning map of Italy), and I was equally happy when MapBox debuted AJ Ashton’s “Pirate Map”. While both these maps are quite beautiful and therefore just plain nice to look at, they seem to be laboring under the misconception that beauty was the only strong point of old cartography.
Because of this, they are missing an important point (in my opinion the most important point) of old maps. “What’s that?” “A very pretty map,” I answered. “It is pretty,” my wife agreed. Enjoy. Like this: Scribble Maps Pro Review. Scribble Maps Pro Review: There are many online applications available that encourage the creation, usage, and sharing of maps among professionals, classmates, and friends. Scribble Maps Pro is one that not only targets both the novice and expert map creator, but unlike its similar counterpart Google Earth Pro, it doesn’t require any special downloads - and it’s free. Its ease of use and accessibility makes it one of the most popular applications in the education sector, offering users a wide range of capabilities, such as marking up maps, measuring distances, importing KMLs, Shapefiles, as well as tabular files, adding placemarks, text, images, shapes and more.
Scribble Maps Pro also provides support for Open Street Map and Cloud Made, enabling users to utilize Scribble Map Pro features onto either of these two mapping applications. Basic Mapping Features Scribble Maps Pro has an inbuilt drawing application, offering users display customizability. Usability. The Fulcrum developer API. Smarter Than You Think: U.S. Highways, Mapped Like A Subway System. The graphic language of the London Underground map is so iconic that "[insert any network or process here] visualized as a London Underground map" has become a design cliché. So why are we writing about the latest iteration, a Tube-style map of U.S. interstate highways, created by Cameron Booth? Because, clichéd or not, visualizing this particular system in this way is actually damned useful. The U.S. interstate system actually has a grid-like logic to it: Highways that go north/south are labeled with odd numbers, and highways that go east/west have even-numbered labels.
Not that you’d be able to easily tell, though--much like the London Underground rail system, interstate highways look like an overturned plate of spaghetti when plotted on a geographically accurate map. I remember getting confused all the time when I was a kid living in northern Illinois: I-94 technically goes east/west, but between Chicago and Milwaukee, it actually goes north/south. Click to zoom. GeoDa Center | Spatial methods and tools. When Maps Shouldn't Be Maps. Often, when you get data that is organized by geography — say, for example, food stamp rates in every county, high school graduation rates in every state, election results in every House district, racial and ethnic distributions in each census tract — the impulse is since the data CAN be mapped, the best way to present the data MUST be a map.
You plug the data into ArcView, join it up with a shapefile, export to Illustrator, clean up the styles and voilà! Instant graphic ready to be published. And in many cases, that’s the right call. For example, census maps of where whites, blacks, Hispanics and Asians live in New York City show clear geographic patterns, answering questions like “What areas of the city are more segregated?”
Or “Where is there more diversity?” You can see how Prospect Park is a stark dividing line, with largely white areas west of it, and largely black areas east of it. Maps also a terrific way to let readers look up information about specific places. 1. 2. MAPublisher | Avenza Systems Inc. Planito. Version: 1.20 || Release Date: 2012-01-28 || License: Commercial with demo ($4.99) Planito is your browser for planet Earth (and others).
Planito is your browser for planet Earth (and others). It is an lightweight yet powerful online and offline multi-layered viewer for aerial imagery, maps, placemarks and other geospatial data layers for Earth, Moon and other planets from various data sources. In its simplest form Planito can be used as online and offline viewer for OpenStreetMap-family maps. But there are many more layers available with interesting and useful data for travelers, students and teachers, scientists. Here are only some of them: Wikimapia.org objects, Wikipedia articles, Booking.com hotels, current temperature from weather stations all over the world, Flickr photos and videos, US Topo Maps, earthquakes, volcanoes and impact craters, UNESCO World Heritage sites.
Thanks to extensible architecture more and more layers will become available for existing and new users. Map of Life and CartoDB « The Map of Life. It’s been an exciting month for Map of Life! We had a great time at TDWG 2011 in sunny New Orleans, where John Wieczorek and I presented Map of Life‘s big dream: to use existing maps to make better maps of where species actually are.
John and Aaron Steele also presented some radical ideas about hooking CouchDB and CouchApp together to build simple, powerful applications. Their switch in strategy made us wonder if perhaps we could pull that off with Map of Life, too. It was in this frame of mind that we attended Javier de la Torre‘s demonstration of CartoDB, a Google Fusion Table-like application to store and render mapping data. The more we saw, the more we liked: open-source (and available on GitHub!) , based on PostGIS on PostgreSQL (already our platform of choice), and incorporating Mapnik, the super-fast tile rendering engine we discussed in our last blog post. In so doing, we’ve reaped the rewards of a much smaller, simpler code base. Like this: Like Loading... Mapping with Drupal. Design Transit Map-Style Graphics. Transit maps like the London Underground “Tube” diagram or the New York subway map are an integral part of life in cities with public transportation. Their bright colors, large type and simplified route lines allow complex travel information to be quickly and easily understood by commuters and tourists alike.
Recently, the subway map has also become a popular metaphor for infographic design, especially for timelines or for depicting other complex networks. I’ve had two such diagrams featured on Visual.ly, both of which have been very well received: the Eisenhower Interstate Highway system (below) and the older U.S. Numbered Highway system. In the course of creating these, as well as several other popular (but unofficial) transit maps for various cities over the last four years – Portland, Oregon, Washington, D.C., and Boston among them – I’ve developed some guidelines and techniques for creating beautiful transit maps.
